Excellent, as always.

Thanks for sharing !

One question regarding migrating to new appliances.

In my scenario, I have single site running dual orchestrator.
As I understand, I can add new appliance inside my security group even if it's not supported for production based sk162373.

Let's say I have 2 SGM 15600 on my single site, and I want to migrate to 9000 series.
If I put 1x 9000 inside my SG, production traffic is supposed to be handled by this 9000s without impact ? Correct ?

But at the end of the migration, I still need to reboot all in the same time to be able to allocated correct SND core number, still correct ?


If yes, smooth indeed, but not totally transparent and still need a maintenance windows as we have a real cut at a moment 

Thanks

I've recently tested a similar scenario, dual site each with dual orchestrators, but the same 15600 to 9000 series appliances.

Once all SGMs were swapped to the 9000 series "asg diag verify" fails the Core Distribution tests with "Ppak cores inconsistency" and "CoresXL + ppak exceed physical"

Had to reboot all SGMs after reconfiguring the CoreXL instance counts with cpconfig. I did find the new 9000 series appliances rebooted much faster than the 15600s. Was approx 6min in my lab.

Also interested to know if there is a smoother way for migration purposes to sort the CoreXL config, or if we just have to take the full outage.
